On a concrete floor, the pad is glued in place, so big chunks of pad will remain stuck to the floor. To remove them, use a floor scraper. Purchase Goo be Gone to assist you in removing the chunks of pad.

We carpeted our front porch because the cement got so slick when it rained. I like the looks of the carpet and feel safer walking on it rather than the wet slick concrete. I am sure the glue will be hard to get off....good luck!
